Mechanism for turning skin cells into blood stem cells uncovered

Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project. "This is a first step on the way to generating fully functional blood stem cells in a petri dish which, ...

Activating a new understanding of gene regulation

Regulation of gene expression—turning genes on or off, increasing or decreasing their expression—is critical for defining cell identity during development and coordinating cellular activity throughout the cell's lifetime. ...

Gene network lets plant roots handle nitrogen

With robotics, computers and advanced genetics, researchers at the University of California, Davis and Cold Spring Harbor Laboratory are unraveling how plant roots take up and metabolize nitrogen, the key to plant growth ...

Regulating gene transcription using light

Researchers led by Mustafa Khammash have developed a new method that uses blue light to control the transcription of DNA into RNA in single cells. The technology could also be used in tissue engineering and stem cell research.

Engineering plants for a sustainable future

In the search for sustainable materials, the day-to-day structures of plants could help replace polluting materials and plastics with ones that are less detrimental to our environment.

Finding the proteins that unpack DNA

A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions. The method, ...
